  • BASIC DESIGN SELECTION TABLES Ball Screws Aircraft

    The first order critical speed of the screw is the lowest natural traverse frequency. (The second, and higher, order natural frequencies are normally an order of magnitude above all ballscrew operating speeds.) The maximum safe operating speed of a ballscrew assembly for normal operation is 80% of the critical speed provided the ball speed
